CT Axial From Top (Vertex) to Bottom (Base of Skull)	Comments
	A place to look for evidence of Subdural collections of blood which acutely are dense and bright white and become darker with time. Appreciate the sulcal patterns here high up near the primary motor cortex.
	Look for subdurals at this level. Look for any density that could be blood in the sulci which could be seen with a convexity type subarachnoid. This is also the level where parafalcine positioned anterior cerebral artery infarction may be seen.
	As above
	As above

	This is a cross section through outer grey matter and sulci and gyri of the cortex and the dark inner matter which is the the centrum semiovale and is a mass of white matter, superior to the lateral ventricles/corpus callosum, present in each of the cerebral hemispheres under cerebral cortex. It has a semi-oval shape and contains projection, commissural, and association fibers. Inferiorly these fibres are continuous with the corona radiata.


	This is the corona radiata which is a white matter sheet that continues ventrally as the internal capsule and dorsally as the centrum semiovale. This sheet of both ascending and descending axons carries most of the neural traffic from and to the cerebral cortex.

	Can see midline falx separating hemispheres. The lateral ventricles are visible with some asymmetrical calcified choroid plexus. Surrounded by the fibres of the corona radiata

	As above. The beginning of the cerebellum is seen in the posterior fossa.
	Level of the midbrain. This is V shaped. Sometimes the Circle of Willis (COW) and MCAs is best seen at this level depending on the slice taken. If not seen check the slice above or below. The cerebellar hemispheres are seen.
	Level of the upper pons and temporal lobes can be seen. The COW is at this level. The slightly dense basilar artery can be seen lying in front of the pons in the midline. This patient had no symptoms and this is a normal scan.The cerebellar hemispheres are seen.
	Can see temporal lobes as well as frontal lobe. Basilar artery and pons. Cerebellum posteriorly.
	Can see temporal lobes as well as frontal lobe. Basilar artery and lower pons. Cerebellum posteriorly.
	Basilar/Vertebral artery. Medulla and Cerebellum posteriorly. Frontal and temporal lobes.
	Medulla and lower cerebellum posteriorly. Frontal and temporal lobes.
	Medulla seen as it becomes spinal cord at foramen magnum
